Hey Hey is usually live though??? They have live crosses, places people have to show up to to win stuff that they only announce during the show, and even emails sent in during the show that they read.
I've asked for time details, but may just fly in for the whole day just to be sure, and overnight it if it is live (finishes at 9.30, which might be too late to fly back out).
Thanks for that description though. For a free comedy show, I'd think, the longer the better?
